Title: Issue #4819 'uninitialized constant ActiveRecord::Deprecation in Rails3.2.1'

in /active_record/connection_adapters/abstract/schema_statements.rb line 429

```ruby
if table_exists?(si_table)
ActiveRecord::Deprecation.warn "Usage of the schema table `#{si_table}` is deprecated. Please switch to using `schema_migrations` table"

old_version = select_value("SELECT version FROM #{quote_table_name(si_table)}").to_i
assume_migrated_upto_version(old_version)
drop_table(si_table)
end
```

It called 'ActiveRecord::Deprecation.warn',
It is typo of 'ActiveSupport::Deprecation.warn'.

Since MyApp was so old (ver1.2.6),
it had schema_info table, so I came accross this typo.

Thanks to Mr.Arun Agrawal, I got a confidence.
I love Rails so much, so I decided to fix this pretty typo.

If my action helps someone, it will be my pleasure.

This website is to encourage my country Japan to fight with the disaster in 2011/3/11.
Thanks to Rails, we could have released this web-site on the day 4 days after the disaster.
